Hi

 

I'm trying to update our conda-forge feedstock to the latest version of our
STIR software. However, all MacOS builds fail when calling swig to generate
the Python wrapper:

 

Assertion failed: (replace_count), function Swig_smartptr_upcast, file
Modules/utils.cxx, line 177.

 

However, Linux and Windows builds work fine. All of them use conda-forge
builds of swig 4.2.0

 

Anyone any suggestions where this could come from?

 

Kris

 

PS: STIR is rather large, and I don't have access to a Mac to try to cut
down where this happens.

 

PS: The full command line to call swig (and some more info) is on set to
current master after merge of TOF (so 6.0.0 pre-release) by KrisThielemans
<https://github.com/conda-forge/stir-feedstock/pull/105> . Pull Request #105
. conda-forge/stir-feedstock (github.com), but is essentially

 

swig4.0 -python -outdir . -c++ -builtin -interface _stir -o
stirPYTHON_wrap.cxx stir.i

 

(It turns out that at least on Linux, swig4.0 is linked to swig. The name
swig4.0 is rather confusing for swig 4.2.0, but ok).
